A Remote Control Relay is an electromechanical device that allows users to switch electrical circuits on and off using remote signals. Unlike traditional relays, which are operated manually or by direct electrical input, Remote Control Relays are designed to respond to signals transmitted via wireless communication methods (such as radio frequency, Wi-Fi, or Bluetooth) or wired protocols (like Ethernet or serial communication). This added functionality makes it ideal for situations where manual control of devices or systems is impractical or inconvenient.
